How to Replace a Freestanding Ice Maker Electronic Control Board

 

file

This DIY repair guide explains how to replace the electronic control board in a freestanding ice maker. The electronic control board is the "brains" of the ice maker, activating components such as the compressor, water inlet valve and pumps as needed to make ice. When the electronic control board stops working, the ice maker won't recirculate water or make ice.

Because problems with parts other than the electronic control board can have the same symptoms, have a service technician test the electronic control board to confirm that it's the cause. If the control board isnt' working, replace it with the manufacturer-approved replacement part.
